How to change colour of blue highlight on select box dropdown

Solution 1:

Yes, you could change the background of select but you will not be able to change the highlight color (when you hover) by using CSS!

You have few options:

1. Is to convert select into ul, li kind of select and do anything you want with this.

2. Use libraries like Choosen, Select2 or jQuery Form Styler . These allow you to style in much more broad and cross-browser way.

Solution 2:

I believe you are looking for the outline CSS property (in conjunction with active and hover psuedo attributes):

/* turn it off completely */
select:active, select:hover {
  outline: none
}

/* make it red instead (with with same width and style) */
select:active, select:hover {
  outline-color: red
}
